We are delivering the best of settings panel for RestaurantPress in the next major update where you can re-size and crop both thumbnails and grid images with your own preference skill and its interface will look like this. Please have a patience 🙂

I changed the image size in the new menu but my page still shows the big image =( I also tryed the resize thumbnails plugin but no effect took place.

See my page:http://www.tinaundjanheiraten.de ( plugin used at Hochzeitsmenü) The black image is just 50x50px.In the settings I changed the size to 100x100px but the image on the page is still 600x600px, why?

Recently I have test the image on your site but I couldn’t find any RestaurantPress plugin currently active. Please do activate the plugin and let me know. For tip purpose: You need to choose the “Hard Crop” in image setting.
